Browser versions : Opera 9.52 and Google Chrome 0.2.149.29
There’s not a lot of detail available ont what, exactly, this benchmark tests but I included it as it seems fairly well known. Oh, and Opera wins this one 🙂 (lower numbers are better).
Another pure-JS benchmark. Again, lower is better.
Note : I had to do some hacking to get it to run in Opera because the test page contains an unsecaped &em;i&em; tag embedded inside a ‘name’ attribute (which is bad and definitely not valid XHTML).
